Structural and Electrical Properties of Heteroepitaxial HgCdTe/CdZnTe/GaAs/Si

, 1989
The structural and electrical properties of heteroepitaxial HgCdTe/CdZnTe/GaAs/Si were evaluated using high-resolution x-ray diffraction techniques and Hall-effect measurements as a function of temperature. Significant tilting of the layers was found for

The influence of growing in a hydrogen atmosphere on the micromechanical properties of Cd1-xZnxTe single crystals

Фізика і хімія твердого тіла
У статті досліджено вплив водневої атмосфери під час росту кристалів Cd 1–x Zn x Te (CZT) на їхню мікротвердість та стійкість до руйнування. Ми виявили, що мікротвердість кристалів, вирощених у водні, вища порівняно зі зразками, отриманими в інертному ...

Dynamics of native oxide growth on CdTe and CdZnTe X-ray and gamma-ray detectors

Science and Technology of Advanced Materials, 2016
We studied the growth of the surface oxide layer on four different CdTe and CdZnTe X-ray and gamma-ray detector-grade samples using spectroscopic ellipsometry. We observed gradual oxidization of CdTe and CdZnTe after chemical etching in bromine solutions.
